function | Pectin methylesterase (PME) inhibitor that can target PMEs (e.g. PME2 and PME3) in a pH-dependent manner, mainly in slightly acidic conditions (pH 6.3 and 5.0) but not at pH 7.5; this processus relies on changes in the protonation of amino acids involved in intermolecular and intramolecular interactions (PubMed:19097903, PubMed:36147700). Regulates de-methylesterification of pectins in the apical meristem and affects primordia formation and phyllotactic patterning (PubMed:19097903). |
similarity | Belongs to the PMEI family. |
tissue specificity | Expressed in apical meristem. |
